My 1991 Honda Accord SE driver’s door will not open, as if it is locked. A good lock shop says it has a small part broken in the electric lock mechanism ($450+). A Honda dealer says, since the lock button on the door rises and falls when the lock switch is activated, it is not the mechanism but the linkage ($200+). Help!

(I listen to Car Talk every Saturday in Seattle. It helps assuage the guilt piled on me during the pledge drive.) SGCB
